Abstract

PURPOSE: To obtain a light weight shear soil-box with a small friction coefficient capable of following movement of the ground by a constitution wherein a plurality of frames are piled up via bearings and loaded on a table and soil is placed on the frames, whereas the table is vibrated. CONSTITUTION: A plurality of frames 5 are piled up and loaded on a table 3 to form a shear soil-box 1. Soil 7 is placed in the soil-box 1. The frames 5 are piled up such that bearing 13 are provided between metallic plates 11. Friction coefficients between the frames 5 become small so that the soil-box 1 sensitively follows movement of the ground. Angle pipes 15a, 15b are bonded to each other by an adhesive so that influence due to deformation in the manufacturing process is reduced. The smoothness of the frames 5 can be thereby maintained and a prescribed level of rigidity can be obtained. It is thus possible to obtain the light weight soil-box 1 having a certain rigidity by combining the conventional angle pipes 15a, 15b.

According to the present invention, since a plurality of the frames are stacked and mounted on the stand through the bearings between the metal plates of the frame on the frame provided with the metal plates on the upper and lower surfaces, the space between the frames is increased. Friction is extremely small. Since the frame uses a bonding method with high processing accuracy, it maintains a flat surface and reduces friction. A lightweight member having a sufficient cross-sectional performance is adopted so that it is not affected by the deformation of the frame in the gravitational field. With the above, a highly accurate vibration test becomes possible.
